problem with display {sampling} value

[podly]

It is impossible to display {sampling} value. I think, there is a bug in display_fields.py

line 264:

super(BitRateField, self).__init__(width=width, **kwargs)

should be:

super(SamplingField, self).__init__(width=width, **kwargs)

It would be also nice to have possibility to display rest of 44100:16:2 - maybe {depth} and {channels} ?

Hi!

Thanks for the report, I've fixed the call to super().

Could you give an example of what you'd like to display from {depth} and {channels}?

[podly]

44100:16:2 - {bitrate} - 44100, {depth} - 16, {channels} - 2

You mean:

44100:16:2 - {sampling rate} - 44100, {bit} - 16, {channels} - 2

yap, exactly.

wasnt happy with sample rate being displayed as 44100.00 instead of 44.1 (also wanted 96 not 96.0), so changed to this:

def _format_sampling(self, sampling='44100:16:2'):
    rate = float(sampling.split(':')[0]) / 1000
    return ('%f' % rate).rstrip('0').rstrip('.')

to get depth and channels I added this code in display_fields.py.

@register_field
class DepthField(Field):
base_name = 'depth'
target_hooks = ['status']

def _format_sampling(self, sampling='44100:16:2'):
    rate = sampling.split(':')[1]
    return '%.0f' % float(rate)

def __init__(self, **kwargs):
    width = len(self._format_sampling())
    super(DepthField, self).__init__(width=width, **kwargs)

def __init__(self, **kwargs):
    width = len(self._format_sampling())
    super(DepthField, self).__init__(width=width, **kwargs)

def add_to_screen(self, screen, left, top):
    return screen.add_string_widget(self.name,
        self._format_sampling(), x=left, y=top)

def hook_changed(self, hook_name, widget, new_data):
    if hook_name == 'status':
        self.status_changed(widget, new_data)
    super(DepthField, self).hook_changed(hook_name, widget, new_data)

def status_changed(self, widget, new_status):
    txt = self._format_sampling(new_status.get('audio') or '0:0:0')
    logger.debug(u"Setting widget %r to %r", widget.ref, txt)
    widget.set_text(txt)

@register_field
 class ChannelField(Field):
base_name = 'channel'
target_hooks = ['status']

def _format_sampling(self, sampling='44100:16:2'):
    rate = sampling.split(':')[2]
    return '%.0f' % float(rate)

def __init__(self, **kwargs):
    width = len(self._format_sampling())
    super(ChannelField, self).__init__(width=width, **kwargs)

def __init__(self, **kwargs):
    width = len(self._format_sampling())
    super(ChannelField, self).__init__(width=width, **kwargs)

def add_to_screen(self, screen, left, top):
    return screen.add_string_widget(self.name,
        self._format_sampling(), x=left, y=top)

def hook_changed(self, hook_name, widget, new_data):
    if hook_name == 'status':
        self.status_changed(widget, new_data)
    super(ChannelField, self).hook_changed(hook_name, widget, new_data)

def status_changed(self, widget, new_status):
    txt = self._format_sampling(new_status.get('audio') or '0:0:0')
    logger.debug(u"Setting widget %r to %r", widget.ref, txt)
    widget.set_text(txt)

Hi, I am new come to here.^0^ As above comment, I had add the code to the display_fields.py and modify the mpdlcd.conf as follow, but the 2 fields is not works, is other need to modify to show it?

pattern2 = {depth}{channel} {elapsed} {song format="%(title)s",speed=2} {state}

Many thanks to all concerned for the opportunity to display the details of the track playing - just one small problem. Having made the changes as per sprocket 1597 everything works well until crashing when playing a DSD file. - I think there may be other files that cause problems but I have yet to track them down.
